Molecular sieves are regenerated by heating to ______________ °C?
Correct answer: B. 200-330
- A. < 150
- B. 200-330
- C. > 500
- D. > 1000
Explanation
Molecular sieves are commonly regenerated by heating in roughly the 200 to 330°C range, often with a purge gas to remove the desorbed moisture. Higher temperatures are unnecessary for ordinary regeneration and may damage the sieve.
